CHAIR SEAT.

Application filed January The object of this present invention, briefly stated, is to provide a chair seat of newand novel construction, which is light in weight,strong and durable in construction,

attractive in appearance, and adapted to give a maximum of comfort to the user thereof.

More specifically stated, my object is to provide a chair-seat in which the body or frame is made of a single piece of laminated material; in which the bottom frame of the cushion is in the nature of an endless hoop made ofa single section of laminated material; and the novelmeans by which the cushion isremovably and resilientlymounted in the body or frame.

Other minor objects and particular features of the invention will be suggested in the courseof the following description, and that which is new will be correlated in the appended claim. 7

The preferredmeans for carrying out the principles of myinvention in a practical manner is shown in the accompanying drawings, in which,Figure 1 is a plan view of the base, with the cushion removed. F igure 2 is a vertical cross section of the body taken on the line 22 of Fig. 1, also showing the cushion in place and as taken in cross section. Figure 3 is a bottom plan of the cushion member of the seat. Figure 4 is a perspective enlarged detail view of one of the supporting brackets or hangers. Figure 5 is a detail view showing a cross sec tion of the cushion frame.

Similar indices denote like out the several views.

3 parts through- In order that the construction, the opera-1 tion, and the several advantages of this in vention may be more fully understood and appreciated I will now take up a detailed description thereof, in which I will set forth the same as comprehensively as I may.

The main portion comprises the base 1 which is substantially in the nature of a hollow square with rounded corners, and it is built up of a plurality of layers of wood veneer stock, with the layers glued together, and it is preferably formed of one continuous length of material wound about a form E0 to the shape shown.

Each of the members 2, 3, 4 and 5 forms a leg and foot, the latter two members continue upward forming the posts for the back, but with these members 2, 3, 4 and 5 6 this invention is not concerned.

Securedto the inner faceofthe base 1, h

and located at each .corner thereof, and extendingtherebelow, are the four brackets 6,

7 8 and 9. .Said brackets are all identical with each other, each having a vertical portion and tllOllZOnttll portion, which portions are at right-angles to each other, and

said portions are reinforced and strengthened by a rib, as the respective ribs a, b, c and d. r y

v The outer end portion of each of the horizontal parts of said brackets is enlarged forming a circular face or plate 6, f, g and 71,, respectively. Said brackets are each secured to the inner face of the base 1 by'a plurality ofscrews 20, which are inserted through apertures 19 in the vertical portions of said brackets.

Formed integral'and concentric with each face 6, f,.gand hare the upwardly extendmg cone-like1lugs 10, 11,12 and 13."

Numerals 14, 15,16 and 17 denote the respective helical springs, the lower ends of which fit around the respective lugs 10, 11, 12 and 13, where they are secured each by a cotter-pin 18, with the lower ends of said springs resting on their respective faces 6, f, g and h.

Each two of said springs is connected at their upper portions by a rod or wire, 23, 24, 25 and 26, although in some instances vthis may be dispensed with.

Reinforcements 21 and 22 are secured to the outer'faces of the two sides of the base l 1, and they extend between the respective front and rear legs, substantially as shown. We now have'the parts of the body of the seat assembled as in Fig. 1, ready to receive thehremovable cushion in connection therewit 3 The cushion, shown in Figs. 2 and 3, comprises a substantially square run 27, with rounded corners, corresponding in shape with the base 1, but of less horizontal'dimensions, and it is of such dimensions as to fit loosely inside the base 1, and it is ed to rest on the upper ends of the springs 14, 15, 16'and 17.

Stretched across the inside of the rim27 and secured thereto are the various strips of Webbing 28, or other material. Resting on the Webbing are a plurality of coil springs 29, and covering said springs and in contact with the upper ends thereof is the padding 30. Covering said padding, and extending downward to enclose the springs 29, and se cured to the rim 27, is the upholstering material 31.

A plurality of lugs 32 are provided, which lugs correspond with the lugs 10 11, 12 and 13, and they extend down from the underside of the rim 27 and fit in the upper ends of the springs 14, 15, 16 and 17, substantially as shown in Fig. 2.

From the above it will be seen that I provide a chair seat construction wherein a person seated on the cushion will not only be supported by the springs 29'as in the usual manner, but that the entire cushion and the load will be supported by the springs 14, 15, 16 and 17, thereby providing a two-fold resiliency for the person seated on the cushion.

This construction also provides means whereby the cushion may be instantly removed by simply lifting it upward, after which the interior of the base-rim, and the parts attached thereto, may be easily cleaned, as well as the cushion.

Having now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, is-

A chair seat including a base frame, legs for supporting the frame, a bracket secured to the inner face of each corner portion of the frame, each of said brackets including a vertical portion which contacts with the inner face of the base and to which it is secured, a horizontal portion extending inward from the lower end of the vertical portion and integral therewith, a rib located in the angle formed by the vertical portion and the horizontal portion, the outer part of each horizontal member being enlar ed forming a circular plate, and a cone-s iaped lug integral with and extending up from the face of said plate with an aperture formed horizontally through said cone; a coil spring having its lower end fitting around said cone and resting on said plate, a pin inserted through said aperture and extending out at each end with the ends located between coils of its spring; rods connecting the upper ends of said springs and spacing them apart a cushion member adapted to lit inside said base, a plurality of coil springs located vertically in the cushion, said cushion being adapted to rest on the upper ends of the first mentioned springs, the two sets of springs being adapted to operate synchro nously to supporta person seated on the cushion.

In testimony whereof I have hereunto subscribed my name.

SYDNEY PAUL.
